Systems and methods for high-magnification high-resolution photography using a small imaging system

2. The imaging system of claim 1, wherein the imaging system has a thickness including the lens, the first partial reflector, the second partial reflector and the time-integrating sensor, of less than 30 mm.

3. The imaging system of claim 2, wherein the lens has a diameter and the diameter is larger than the thickness of the imaging system.

4. The imaging system of claim 1, wherein the time-integrating sensor is a Charge Coupled Device (CCD) or a Complementary Metal Oxide Semiconductor (CMOS) array.

5. The imaging system of claim 1, wherein the lens, the first partial reflector, the second partial reflector, and the time-integrating sensor are enclosed within a mobile device.

6. The imaging system of claim 1, wherein the lens, the first partial reflector, and the second partial reflector are arranged to produce the focused light when the transmitted light undergoes a desired number of round-trips reflections between the first partial reflector and the second partial reflector.

8. The method of claim 7, further comprising displaying the in-focused image on a screen-of the mobile device.

9. The method of claim 7, wherein the reconstructing the in-focus image-comprises processing the raw image using a background subtraction, high-pass filtering, or deconvolution algorithm.

10. The method of claim 7, wherein a distance between the lens and the sensor is less than the focal length.

11. The method of claim 8, wherein the mobile device has a thickness including the lens, the two or more partial reflectors and the sensor, of less than 30 mm.

12. The method of claim 7, wherein the sensor is a time-integrating sensor.

13. The method of claim 12, wherein the time-integrating sensor is a Charge Coupled Device (CCD) or Complementary Metal Oxide Semiconductor (CMOS) array.

14. The method of claim 12, wherein the lens and the two or more partial reflectors are arranged to produce-the focused light when the transmitted light undergoes a desired number of round-trips reflections between-the two or more partial reflectors.

16. The device of claim 15, wherein the mobile device has a thickness including the lens, the first partial reflector, the second partial reflector and the time-integrating sensor, of less than 30 mm.

17. The device of claim 15, wherein the time-integrating sensor is a Charge Coupled Device (CCD) or Complementary Metal Oxide Semiconductor (CMOS) array.

18. The imaging system in claim 15, further comprising additional lenses placed between the first partial reflector and the second partial reflector.
